History- Five Conservation Authority Flood Forecasting and
Warning Groups were formed in 1998 as a result of recommendations by the Province’s 1997 Red Tape Review Commission.
- These Groups consisted of CA staff from 5 different regions of the Province.
- The main purposes of these groups was to streamline the FFW process, allow for more consistency, and avoid duplication in efforts.
- In 2002, the GTA CA FFW group undertook to develop FFW Standards.

These standards were completed in April 2003.
